Tell me how you check that you have a safe level of hydraulic brake fluid
1. Open a bonnet
2. Identify reservoir
3. Check level against high and low markings
Nissan Micra: With ignition on, the brake warning light will illuminate when the parking brake is applied. If parking brake is fully released and light comes on, this informs the driver of a low level of brake fluid. If brake fluid levels are correct, this may indicate air in the system and vehicle must be checked by a Nissan technician
